Abstract
An improved, two step synthesis, of the importrant chiral templating r eagent 2,6-Dihydroxy-9, 10-dihydro-11,12-dicarbomethoxyethenoanthracen e 3 has been developed with an overall yield of 82% (not optimized). T he reaction features a simple diastereomeric separation to afford the enantiomeric products. The reaction can be scaled up to afford multigr am quantities of the ethenoanthracenes.
